Product details
Overview
SBR0240LP-7 from Diodes Incorporated is a 40 V, 250 mA surface-mount Super Barrier Rectifier (SBR®) optimized for low-voltage DC/DC conversion and power management in space-constrained portable electronics. It delivers ultra-low forward voltage (0.21 V at 10 mA, +25°C), soft fast switching, and operates up to +150°C junction temperature in the X1-DFN1006-2 package.
For engineers reviewing the SBR0240LP-7 datasheet, SBR0240LP-7 pinout, SBR0240LP-7 application, or SBR0240LP-7 equivalent, key selection criteria include forward voltage drop at light-load currents, reverse leakage under 40 V bias, thermal resistance (270°C/W), and compatibility with high-density DFN layout requirements for battery-powered systems.
Technical Context
This Super Barrier Rectifier uses Diodes' patented SBR® technology to achieve Schottky-like forward conduction with enhanced reverse avalanche ruggedness-unlike standard Schottky diodes, it withstands repetitive 5 A surge current (8.3 ms half-sine) without degradation. Its low VF minimizes conduction loss in 3.3 V and 5 V buck converter outputs.
The device is rated for 40 V peak repetitive reverse voltage (VRRM) and exhibits only 0.5 µA typical reverse leakage at 25 V, +25°C. Its 270°C/W junction-to-ambient thermal resistance assumes FR-4 PCB with 2 oz copper and minimum recommended pad layout per Diodes' outline X1-DFN1006-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - maximum non-repetitive reverse blocking capability; suitable for 3.3 V–5 V output rails with margin against transients |
| IO(AV) | 250 mA - average rectified current rating; supports continuous operation in low-power PMIC output stages |
| VF @ 10 mA | 0.21 V - ultra-low forward drop enables >95% efficiency in light-load DC/DC converters |
| IR @ 25 V | 0.5 µA - minimal leakage preserves battery life in always-on subsystems |
| RθJA | 270 °C/W - thermal performance defined on standard FR-4 board; requires careful copper pour design for >100 mA sustained loads |
| TJ Range | −65°C to +150°C - extended junction temperature supports automotive cabin and industrial ambient environments |
| IFSM | 5 A - robust surge handling allows use in circuits with high-capacitance output filtering |
Pinout & Package
Package: X1-DFN1006-2 - 1.0 mm × 0.6 mm, 0.25 mm nominal height, 2-terminal leadless plastic package with NiPdAu-plated copper leadframe and UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Input current entry point | Connected to switch node or input rail; requires thermal pad connection to PCB copper for heat dissipation |
| Cathode (Pin 2) | Output current exit point | Connected to output capacitor and load; polarity critical-reverse connection causes catastrophic failure |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF at 10 mA | 0.21 V - reduces conduction loss by ~40% vs. standard Schottky diodes in standby-mode power paths |
| Super Barrier (SBR®) technology | Patented structure combining Schottky and PN junction benefits - achieves soft recovery without snubber networks |
| +150°C operating junction temperature | Enables placement near hot components (e.g., power inductors, MOSFETs) without derating in compact layouts |
| Lead-free, halogen-free, antimony-free | Complies with RoHS 3 (2015/863/EU) and automotive "Green" standards - no Br/Cl >900 ppm, Sb <1000 ppm |
Applications
| USB Power Delivery Receivers | Wearable Device Battery Charging |
|---|---|
Use Scenario: Reverse-polarity protection and OR-ing in dual-input (USB-C + battery) power paths of compact wearables. IC Role / Device Role / Timing Role: Low-VF rectifier enabling efficient 5 V input routing while blocking reverse current from battery during USB disconnect. Use Value: 0.21 V VF at 10 mA minimizes voltage drop across protection path, preserving >4.75 V at system input under light load. | Use Scenario: Output rectification in miniature synchronous-buck converters powering Bluetooth SoCs and sensors. IC Role / Device Role / Timing Role: Freewheeling diode replacing body diode of high-side FET in asynchronous mode or during light-load discontinuous conduction. Use Value: Soft switching eliminates EMI spikes seen with fast-recovery diodes, easing EMC compliance in Class B consumer devices. |
| IoT Sensor Node Power Management | Automotive Body Control Module Sub-Regulators |
Use Scenario: Input protection and voltage clamping in energy-harvesting circuits powered by piezoelectric or solar cells. IC Role / Device Role / Timing Role: Low-leakage (0.5 µA @ 25 V) blocking diode preventing reverse discharge of storage capacitors during intermittent source availability. Use Value: Enables >100-hour hold-up time with 100 µF storage capacitance-critical for maintenance-free sensor deployments. | Use Scenario: Secondary 3.3 V supply rectification in LIN bus interface modules exposed to under-hood temperatures. IC Role / Device Role / Timing Role: High-temperature-rated rectifier maintaining stable output under +125°C ambient conditions with minimal derating. Use Value: Full 250 mA current capability retained up to +105°C ambient (per Figure 5), eliminating need for larger packages or forced cooling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT0240L-7 | Same die, but in SOD-123FL package (2.7 mm × 1.7 mm); RθJA = 220°C/W; VF identical at 10 mA | Larger footprint; better thermal performance but incompatible with ultra-dense layouts requiring DFN | Select when board real estate permits and higher thermal margin is prioritized over size |
| SD103AWS-7-F | Standard Schottky; VF = 0.45 V @ 10 mA; IR = 5 µA @ 25 V; no avalanche rating; RθJA = 300°C/W | Higher conduction loss, higher leakage, lower surge robustness; not qualified for automotive temp range | Acceptable only in cost-sensitive, non-automotive, non-surge-prone applications where 0.24 V extra drop is tolerable |
Compared with SBRT0240L-7 and SD103AWS-7-F, the SBR0240LP-7 uniquely balances ultra-small size, sub-0.25 V forward drop at microamp-level currents, and 5 A surge capability-making it optimal for miniaturized, thermally constrained, and reliability-critical power paths.

FAQ
What is the maximum continuous forward current for SBR0240LP-7 at +85°C ambient?
At +85°C ambient temperature, the maximum continuous forward current is approximately 180 mA. This is derived from Figure 5 (Forward Current Derating Curve), which shows linear derating from 250 mA at 25°C to 0 mA at ~175°C ambient-yielding ~180 mA at 85°C on a standard FR-4 board with 2 oz copper.
Does SBR0240LP-7 require a thermal pad connection to PCB?
Yes-the X1-DFN1006-2 package relies on the exposed copper pad beneath the die for thermal conduction. The datasheet specifies a recommended pad layout (C = 0.70 mm, G = 0.30 mm) and states that thermal resistance (RθJA = 270°C/W) assumes this layout on FR-4 with 2 oz copper. Omitting the thermal pad increases junction temperature significantly.
Is SBR0240LP-7 qualified to AEC-Q200?
No-SBR0240LP-7 is not AEC-Q200 qualified. It is a commercial-grade part. For automotive applications, Diodes offers the Q-suffix variant SBR0240LPQ-7, which is manufactured in IATF 16949-certified facilities and qualified to AEC-Q200 Grade 1 (−40°C to +125°C).
Can SBR0240LP-7 be used as a replacement for a 1N5817 in a 5 V supply?
Yes, but with caveats: SBR0240LP-7 has lower VF (0.21 V vs. ~0.45 V) and smaller package (1.0 × 0.6 mm vs. DO-41), improving efficiency and density. However, its 250 mA average current rating is lower than the 1N5817's 1 A, so it is only suitable in low-current 5 V paths (<250 mA). Layout must accommodate DFN soldering and thermal pad.
